This dissertation was to develop effective graphene-based nanofluidic devices by developing scalable fabrication methods and elucidating proton transport mechanisms.

The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…

Few researchers see potential in research on glioblastoma, an incurable brain tumour. Alexander Kros brought together colleagues who are up to the challenge. European research funder ERC recently made 10.6 million euros available, a year earlier NWO provided 3 million euros. ‘In six years, we certainly…

This thesis focuses on the application of lipid-based nanomedicine in drug delivery, including small molecular antitumor drugs and biomacromolecules including mRNA, and evaluates their biological performance.

Viral diseases constitute one of the major challenges in modern medicine. Membrane-targeting have broad-spectrum potential and could distinguish viral membranes from the host cell plasma membrane by the difference in membrane curvature.

The adsorption of D2 and CO2 on catalyst surfaces is studied using a molecular beam in ultra-high vacuum.

As of this month, Kim Bonger has been appointed Professor of Chemical Biology. As a first-generation academic, she’s especially grateful. ‘I wasn’t exactly a top student at school. I never could’ve imagined this.’

Researchers from the Leiden Institute of Chemistry show proof of principle that live-cell structural changes and metabolic processes can be followed in real time with NMR spectroscopy. They performed their study on photosynthetic green algae that are metabolically flexible and can sustain energy generation…

Deficiency of glucocerebrosidase (GBA) underlies Gaucher disease, a common lysosomal storage disorder. Carriership for Gaucher disease has recently been identified as major risk for parkinsonism. Presently, no method exists to visualize active GBA molecules in situ. We here report the design, synthesis…

Active-site directed probes are powerful in studies of enzymatic function. We report an active-site directed probe based on a warhead so far considered unreactive.

The aim of this thesis is to explore the use of Bioorthogonal Antigens to study the cross-presentation pathway.

This Thesis describes the design, synthesis and evaluation as glycoprocessing enzyme inhibitors of focused libraries of iminosugars.

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

Theorists have recently made substantial progress in simulating reactive molecule-metal surface scattering but still face major challenges. The grand challenge is to develop an approach that enables accurate predictive calculations of reactions involving electronically excited states with potential…

The probability for dissociation of molecules on metal surfaces, which often controls the rate of industrially important catalytic processes, can depend strongly on how energy is partitioned in the incident molecule. There are many example systems where the addition of vibrational energy promotes reaction…

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

Russian Cellist and ACPA researcher Maya Fridman is organizing many benefit events together with Russian and Ukrainian musicians to raise funds for Giro 555 for Ukraine.

Leiden University regularly confers honorary doctorates, and presents awards and prizes.

The Leiden Institute of Chemistry (LIC) offers a unique tailor-made programme in Chemistry. You can customize the programme to your own interests and ambitions with the help of your own personal mentor. Your study will focus on either Chemical Biology or Energy & Sustainability. During the Master's…

Four Leiden researchers have each been awarded a consolidator grant of up to 2 million euros by the European Research Council (ERC). They carry out research on a diverse range of subjects, from gender stereotyping in the field of science to making sugar molecules.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

The Leiden Institute of Chemistry organises and participates in several programmes for high school students and teachers.

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

Although sugars are widely used in biological and medical research, their synthesis is still badly understood. Jeroen Codée has received a Vici grant of 1.5 million euros for systematically studying the production of sugars. ‘I want to genuinely understand the reactions.’

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars (exoplanets). They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems. This way they address…

Coordination chemistry is the chemistry of metal atoms
